Because it came out last year that Cindy had control of the gravesite. The current article you are posting to states: " Sheehan also said that Casey's grave site was now being handled by her soon-to-be ex-husband Patrick."
How exactly does one parent have control of a gravesite over another parent? I seriously don't understand why the family doesn't just step in and fix this. And how is it that she has sole control over any inheritance? She's a nut for sure, but I can't reason why the rest of the family didn't step up and do something about it. She is not Casey's only family member.
